Java多线程模拟储蓄卡账户流水

Question

模拟一个储蓄卡账户，起初额度是100元，模拟取现、存款等多次操作。 1.可以先取出1元，再存入1元，有1000次以上的流水即可。 2.输出结果可为示例：”向账户取了1元，账户还有X元“，或者”向账户存了1元，账户还有X元“。其中X为当前储蓄卡内的余额。 3.为了方便查看结果，流水次数最好以10的倍数。

Answer 1

我刚好写了一个，看看是不是你要的

 public class AccountTest {
    public static void main(String[] args) {
        Account account=new Account();
        Bank bank=new Bank();
        bank.setAccount(account);
        Thread t1=new Thread(new PeopleIn(bank));
        Thread t2=new Thread(new PeopleOut(bank));
        t1.setName("张三");
        t2.setName("张三的老婆");
        t1.start();
        t2.start();
    }
}
class Account{
    private int balance=100;
    public int getBalance(){
        return this.balance;
    }
    public void amountOut(int amt){
        balance=balance-amt;
        System.out.println(Thread.currentThread().getName()+"取款"+amt);
    }
    public void amountIn(int amt){
        balance=balance+amt;
        System.out.println(Thread.currentThread().getName()+"存款"+amt);
    }
}
class Bank{
    private Account account;
    private boolean flag=false;
    public void setAccount(Account account){
        this.account=account;
    }
    public Account getAccount(){
        return account;
    }
    public synchronized void moneyOut(int amt) {
            if(flag==false){
                try {
                    //System.out.println("老公还未存钱，余额不足。");
                    this.wait();
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
            try {
                Thread.sleep(100);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            if(this.account.getBalance()>0){
                account.amountOut(amt);
                System.out.println("账户余额"+this.account.getBalance());
            }else {
                System.out.println("余额不足，无法完成取款。");
            }
            this.flag=false;
            this.notify();
        }

    public synchronized void moneyIn(int amt) {
            if(flag){
                try {
                    //System.out.println("老婆还未取钱，无法存钱。");
                    this.wait();
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
            try {
                Thread.sleep(100);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            if(this.account.getBalance()<100){
                account.amountIn(amt);
                System.out.println("账户余额"+this.account.getBalance());
            }else {
                System.out.println("账户金额已满，无法完成存款。");
            }
            this.flag=true;
            this.notify();
        }
    }

class PeopleIn implements Runnable{
    private  Bank bank;

    @Override
